Lette/rs .Patent No. 92,196, dated July 6,1869.

IMPROVEMENT IN' KNIFE-HANDLE BOLSTER.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it mwy conc-era:

Be it known that I, W. P. LATHROP, of West Winsted, in the county otLitchtield, and State of Connecticut, have invented a new and improved Knife-Handle Bolster; and I do hereby declare that vthe following is a full and exact description otl the' same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Thisinventicn relates to an improved method of at'- taching the blades of ordinary case-knives to their handles; and consists .mainly in a peculiar" construction ofthe bolster, whereby greater strength and durability are obtained, as will hereinafter more fully appear.

ln the drawings- Figure l is aside elevation of a knife, provided with my invention;

Figures 2, 3, and 4, are perspective views of the parts detached; and l Figures 5 and 6, sectional views of the bolster' B.

To enable those skilled in the art tornake and use my invention, I will proceed to describe its construction and opration.

- A represents the blade, with its tang a; B, the boll ster; and C, the handle.

'.lhe bolster B consists of the two side plates, b, connected by the solid hub b, in which is the milled slot b, which extends entirely through the same, forming a suitable orifice for the tang a to enter.

On the inside of' the-hub b, is the mortise c, into which is iitted a corresponding tenon, c,'on -the ends of the handle O.

rlhis latter is also cut away on each side, as shown,

The method of attaching the partsis as follows: The handle is fitted to the bolster as described, and

Athe tang introduced in a-suitable orifice, passing iirst l through the slot in the bolster, and cemented therein. The' inner end of the blade will then fit closely betweenthe lips d d, and bear against the'end ofthe hub b. An orifice is then made through the side plates of the bolster, handle,and tang, and a pin or rivet introduced, which securely fastens the whole.

`The bolster may be of cast or malleable metal, and may be applied to a solid handle, or to scale-tang cutlery.

The. oriiice-in the handle l for the vreception of the tang, is commonly burned out, which chars the wood at the end, and weakens it where considerable strength is required. I form said orifice by suitable machinery, and thereby obviate this difticulty.

lhe mortisec in the bolster is particularly calculated to make an edge-bearing for.th e handle, and prevent the same from splitting.

The projecting lips d d afford great strength, when.

side7pressure is brought to bear on the blade, and the shoulder o, bearing as it does againstthe end of the hub b, makes a iii-n1 bearing, obviating all strain on the tang.

The whole arrangement is one combining strength, neatness, and utility, and is especially adapted to carving and butchers knives, and also to table-cutlery.

, Having thus fully described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

1. The bolster B, having the slot b2, lips d d, mortise c, and side plates b, connected by the hub b, substanti-ally as and for thepmpose speciiied.

-'2. In combination with the above, the handle O, with its tenou c', substantially as described.

This specification signed and witnessed, this 25th day of May, 1869.
